It was well known the most easily physical activity was to the walking. However the data was dependent on experimental setting and environments within several reports case. The Nordic Walking is a great fitness workout for people who are looking for a fun physical activity and maximum health benefits combined with safety. Then it was well known therapeutic exercise as a walking was effected of prevention both lifestyle disease and osteoporosis. There are no data in outdoor Nordic walking by ambulatory Electromyography (EMG). The purpose of this study was to evaluate the EMG activity during outdoor field ambulatory recording between nordic walking (NW) and normal walking (W) on same environments. There were sixteen subjects participated in this study. It was monitoring the Heart rate (HR) and Electromyogram (EMG, tibialis anterior, medial gastrocnemius, rectus femoris, biceps femoris, erector spinae, trapezius, biceps brachii, triceps brachii) with both hands nordic pole walking continuously at least one hour recording by portable data logger device (Biometorics, UK) by 1Kz sampling. One experimental trial was to consist of 8 row 3.6 million matrix was saved and DC cut filtered with signal processings. It was caluculated integrated EMG for muscle activity. There were no significant different in heart rate response between nordic walking and without pole normal walking. This present study revealed differences in EMG activity. There were significantly higher (P<0.05) compared with pole walking and normal walking in tibials anterior. It was not showed any differences in erector spinae muscle activity between the nordic walking and normal walking condition. The involvement of the trunk, arm and shoulder muscles during nordic walking accounts for the increase in load distribution work at a given walking speed. Our result demonstrate that Nordic Pole Walking immediately enables in all subjects with voluntary locomotion condition to walk future with less leg muscle activity rather than normal walking. Nordic Pole walking could therefore, be a use exercise strategy for increasing the longer fitness of all healthy subjects.
